    Welcome to the iPhoneForums tutorial on how to re-restore your non-A4 device to a 5.x firmware using SHSH Blobs and redsn0w!

    redsn0w continues to evolve to be far more than just a jailbreak tool, and the latest iteration delivers something the community has been eagerly anticipating since the release of IOS6. iPhone4S owners can now re-restore their devices to previous versions of 5.x firmware provided they have saved SHSH Blobs. Before this tool was released, it was only possible to restore to IOS 6.0.

    This tutorial will demonstrate the re-restore of an iPhone4S from 5.1.1 to 5.1.1. The tool however will support the installation of ANY IOS 5.x firmware from ANY 5.x firmware version currently installed, provided you have the necessary blobs.

    Preparation
    In order to re-restore your device you will need a copy of the version of IOS you with to restore to. In this example it is 5.1.1 for the iPhone4S.
    You can download the files you need from our handy thread. Make sure you pick the right files for your specific device - http://www.iphoneforums.net/forum/i...ple-ios-firmware-download-links-iphone-17213/

    Next, you need to download the latest version of redsn0w from the iPhone dev-team blog here - Dev-Team Blog
    You will need at least version 0.9.15b1 or newer.

    Let's Re-Restore!
    1. Connect your iPhone to your PC and shut down iTunes, if it automatically launches.
    2. Launch redsn0w on your computer and select the "Extras" option (Don't forget to run the executable as an "Administrator" if you are using a Windows PC)

    3. Press the "Even More" button…

    4. Press "Restore"…
    [​IMG]
    5. Press "IPSW"
    [​IMG]
    6. Select the firmware file you with to re-restore, which you downloaded when preparing for this tutorial…

    7. If redsn0w cannot find your blobs automatically, use the "Local" or "Remote" buttons help identify them)

    HEED THE WARNING ABOUT YOUR BASEBAND! Remember, don't do this if you rely on a software or hardware unlock solution unless you know you are safe to proceed!

    8. Marvel as redsn0w works it's magic… :D

    9. Congratulations! Your iPhone has now been re-restored to clean factory fresh IOS 5.1.1 (or whichever firmware you have chosen to re-restore with this method).

    Optionally, if you also want to re-jailbreak the device...
    10. Once you complete the setup Wizard on your iPhone, go back to the main menu on redsn0w, and press "Jailbreak"
    [​IMG]
    11. A few seconds later you will have a freshly restored device with a clean new jailbreak :D

    There you have it. Re-restoration on the iPhone4S!

    Yes, that is how I understand it, reading it here as well as other sites. As long as you have the blobs for whatever version saved. In my case, I have 5.0, 5.1, 5.1.1 saved on Cydia... I can go back to any of the three. Although I am still not brave enough to install ios6 to find out yet. ;) Let the other guinea pigs have it first.

    Yes, as the tutorial states in it...

    It will not downgrade from 6.0 however. That is only possible on the iPad2 IF you also have 4.x blobs. It is not possible for iPhone4S owners to have 4.x blobs.

    :D

    Tested the downgrade on the iPad 2 using 4.3.5 and 5.1.1 to downgrade from 6 to 5.1.1. Also tested the re-restore feature on the 4S. Probably misread it the first time from lack of sleep and screwed it up, but it working the second time

    You can't do it without some form of iOS 4. :/

    SHSH blobs are unique to each device. Its not as simple as copying and pasting it

    Thanks.

    That's unlucky :(

    Seems the best advice to everyone interested in the possibility of jailbreaking in the future is now to always avoid the OTA update method, just in case this jeopardises future downgrade / re-restore opportunities because of the way the APTicket is associated with the Blobs at restore time.

    It seems the APticket flashed in the device cannot be re-used for this hack.
    If the current Firmware was installed via an OTA update or at the factory, it APticket contains the wrong data for this to work.
    your device should be kicked out of Recovery mode once you go back to the redsn0w main menu....

    i got an iphone 4s 5.1.1 Jailbroken with absient, when i bought it was at 5.1.1 and i just jailbroke it and now want to restore it cuz it is getting supper slow... (many tweeks installed)... how should i proceed!!
    thanks a lot

    I got my 4s from t-mobile uk with 5.1.1 already installed. Is there any way I can find out if I will be able to restore without actually trying it?
